Very nice little widget. After looking through all the other tag cloud plugins this is the one I found most flexible.

It just needs a bit of styling on the way it displays on the backend. But it's not important. It does its job!

Thank you very much :D

Great customization!

OST 3D Image Tag Cloud allows you to display your site’s tags using jquery that rotates the image tags in 3D.
It works just like a regular tags cloud, but is more visually exciting. Clicking the tags will take you to the appropriate page. Might not work with less than IE9.
New Configuration options been added to the admin panel. Now the site admin can configure the following options.
<ol>
<li>Title of the Tag Cloud.</li>
<li>Number of tags to be displayed.</li>
<li>Height and Width of the widget.</li>
<li>URL of the image per tag.</li>
</ol>
